Detailed Description

In the following description, numerous details are provided to provide a thorough understanding of the utility model. One skilled in the art, however, will understand that the following description merely illustrates a preferred embodiment of the utility model and that the utility model may be practiced without one or more of these details. In other instances, well known features have not been described in detail so as not to obscure the utility model.

A cooking appliance generally includes a pot (not shown) and a cover. The cover body can be pivotally arranged on the pot body in a hinged mode and the like. When the cover body is covered on the pot body, a cooking space is formed between the cover body and the pot body. Of course, the cover body can also be buckled on the pot body in a removable way. Such a cooking appliance may be an electric rice cooker, an electric pressure cooker, an electric stewpan or any suitable cooking appliance. The cooking appliance may have a plurality of cooking modes, such as a rice cooking mode, a porridge cooking mode, a soup cooking mode, and the like. Steam is generated regardless of the cooking mode. In order to exhaust the steam, the cover is usually provided with an exhaust port. The steam sometimes carries the broth as it passes through the vent, resulting in the formation of bubbles around the vent. The utility model provides a cover body which can comprise a bubble breaker, wherein the bubble breaker can break bubbles formed by steam, and the phenomenon that the bubbles formed by the steam are accumulated to cause overflowing is avoided. According to another aspect of the present invention, there is also provided a cooking appliance having the cover.

In order to understand the structure of the cover in detail, a plurality of embodiments using the cover will be described in detail below.

Illustratively, as shown in fig. 1, the cover body may include an inner cover 100. The inner lid 100 may be made of a metal material, and the inner lid 100 is directly contacted with food materials in the pot body during cooking, so that it is required to select a material which is high temperature resistant and easy to clean. Of course, if possible, the inner lid 100 may be made of a non-metallic material such as high temperature resistant ceramics, plastics, or resins. The inner lid 100 may be provided with an inner lid vent 101. Alternatively, the inner lid 100 may be provided with an inner lid return port (not shown). The inner cap gas discharge opening 101 and the inner cap return opening may be through holes penetrating the upper and lower surfaces of the inner cap 100. The inner lid air outlet 101 may be used to discharge steam generated in the pot. The inner lid return port may be used to return condensed water and/or spilled soup accumulated on the upper surface of the inner lid 100 to the pot. In embodiments that do not include an inner lid return port, condensed water and/or spilled soup may also flow back into the pan through the inner lid vent 101. For convenience, the condensed and/or spilled broth will be referred to hereinafter as liquid. It is understood that the function of the inner lid vent 101 and the inner lid return port may be different, and may be different in structure and distribution. The arrangement of the inner lid vent 101 and the inner lid return port is well known in the art and will not be described in further detail herein.

The cover may also include a bubble breaker 200. The bubble breaker 200 may be disposed above the inner lid 100. The bubble breaker 200 may include a bubble breaking funnel 210. The bubble breaking funnel 210 is in the shape of an inverted funnel. The bubble breaking funnel 210 may have two ends, one end having a larger sized opening and the other end having a smaller sized opening. The opening of the foam breaking funnel 210 with a larger size faces downward, and the opening with a smaller size faces upward, forming an inverted funnel shape. The lower opening (larger-sized opening) of the burst funnel 210 may face the inner lid 100. The upper opening (smaller opening) of the bubble breaking funnel 210 may face upward, and the inner lid vent 101 may communicate with the outside through the bubble breaking funnel 210. In the embodiment shown in fig. 1, the lower opening of the frothing funnel 210 is disposed opposite to the inner lid vent 101, i.e. the inner lid vent 101 is located in the projection of the lower opening of the frothing funnel 210 on the inner lid 100, and the lower opening of the frothing funnel 210 and the inner lid vent 101 are disposed at an interval. In an embodiment not shown, the lower opening of the frothing funnel 210 can also be attached to the inner lid 100 such that the lower opening of the frothing funnel 210 coincides with the plane in which the inner lid air outlet 101 is located. It is understood that the lower opening of the bubble breaking funnel 210 may be horizontally offset from the inner lid vent 101 to extend the distance from the inner lid vent 101 to the lower opening of the bubble breaking funnel 210. Thus, the extended path also has a certain bubble breaking effect. In order to allow the steam discharged from the inner lid vent 101 to enter the bubble breaking funnel 210, a pipe communication may be provided between the lower opening of the bubble breaking funnel 210 and the inner lid vent 101.

The break-foam funnel 210 generally includes a lower head portion 212 and an upper neck portion 214, as shown in fig. 4-5, with the head portion 212 having a larger cross-sectional area relative to the neck portion 214. The cross section of the head portion 212 is not limited to a circle, but may be an ellipse, a polygon, or the like. The side walls of head portion 212 may be straight or curved. The lower opening of the head section 212 is larger in size and the upper opening is smaller in size, so that the gas velocity will increase during the movement of the gas towards the upper opening of the head section 212, the fast flowing gas can generate a larger impact force on the gas bubbles, and the gas bubbles can be broken in the head section 212, so that the gas and the liquid are separated. The neck portion 214 functions to vent the vapor from the vapor and the gas generated by the collapse of the bubbles. The neck portion 214 also provides some cushioning, even if a small amount of gas bubbles have not been broken in the break-out funnel 210, and after entering the neck portion 214, there is an opportunity to break sufficiently under the impact of the high-velocity gas, and the neck portion 214 also provides liquid back into the break-out funnel 210.

Illustratively, although the neck portion 214 is shown as being straight. In other embodiments not shown, however, the neck portion 214 may be curved. Also, the air outlet of the neck portion 214 may be in direct communication with the upper lid 410 on the panel 400 of the cover. Of course, the vent of neck portion 214 may also be spaced from the micro-pressure overcap as shown. That is, the shape and length of the neck portion 214 may be arbitrary. Alternatively, the inner diameter of the lower end of neck portion 214 may be slightly larger than the inner diameter of the upper end of neck portion 214. This may help to increase the velocity of the gas flow within the bubble-breaking funnel 210, thereby increasing the probability of breaking bubbles. It will of course be appreciated that the neck portion 214 may also have a uniform and consistent inner diameter throughout.

Illustratively, the cover may further include a seal 500. The sealing member 500 may seal between the side of the bubble breaker 200 and the upper face of the inner lid 100. The inner lid 100, the seal 500 and the bubble breaker 200 enclose a first chamber 232. The seal 500 may be a gasket. The sealing ring can be sleeved on the bubble breaker 200, and one end of the sealing ring can be tightly connected with the outer side surface of the bubble breaker 200 so as to realize sealing between the sealing ring and the bubble breaker 200; the other end of the sealing ring may be closely attached to the upper surface of the inner cap 100 to achieve sealing between the sealing ring and the inner cap 100. Thereby, a relatively sealed first cavity 232 may be formed between the frothing funnel 210 and the inner cap 100 inside the sealing ring. The first chamber 232 communicates with the bubble breaking funnel 210 and the inner lid vent 101. Thus, the gas entering the first chamber 232 through the inner lid gas outlet 101 can only flow out of the lid body through the bubble breaking funnel 210.

During cooking, the steam is usually mixed with the cooking liquor in a viscous state. The vapor may be discharged from the inner lid vent 101 to generate bubbles, which may enter the bubble breaker 200 from the first chamber 232. Because the foam breaking funnel 210 is in an inverted funnel shape, the head part of the foam breaking funnel 210 is larger in size, and the neck part is smaller in size, so that the gas entering the foam breaking funnel 210 is increased in the moving process of the gas close to the neck part, the gas speed is increased, the fast flowing gas can generate larger impact force on bubbles, the bubbles can be broken in the head part of the foam breaking funnel 210, so that the gas and the liquid are separated, the separated gas is discharged out of the cover body through the neck part of the foam breaking funnel 210, and the liquid flows back to the inner cover 100 along the inner wall of the head part of the foam breaking funnel 210, and finally flows back to the pot body through the inner cover 100.

Therefore, the bubble breaker 200 is arranged in the cover body of the utility model, the bubble breaker 200 comprises the bubble breaking funnel 210 in an inverted funnel shape, even if bubbles generated when gas passes through the air outlet 101 of the inner cover spread into the bubble breaking funnel 210, the flow rate of the funnel effect gas is accelerated when the gas is close to the neck part of the bubble breaking funnel 210, the flowing gas can impact the bubbles in the bubble breaking funnel 210, so that the bubbles are broken more easily, and the phenomenon similar to overflowing is avoided. The sealing member 500 is sealed between the side surface of the bubble breaker 200 and the inner lid 100, and prevents gas, bubbles, and the like from entering other portions of the lid body. After entering the first cavity 232 surrounded by the inner lid 100, the sealing member 500 and the bubble breaker 200 through the inner lid vent 101, the bubble breaker 200 can be discharged to the outside of the lid body only through the bubble breaking funnel 210, so that the bubble breaker 200 can fully function. In addition, the bubble breaker 200 and the inner cover 100 are separately arranged, so that the processing difficulty of the cover body can be reduced, and the product cost is reduced.

As shown in FIG. 2, since the frothing funnel 210 has an inverted funnel shape, the angle α between the side wall of the head portion 212 and the side wall of the neck portion 214 of the frothing funnel 210 is at 0^°～180^°In the meantime. Preferably, the angle α between the sidewalls of the head portion 212 and the neck portion 214 can be 120^°～150^°In the meantime. Within this range, the side walls of the head portion 212 can act as a barrier to the gas bubbles, allowing the gas bubbles to more easily stay within the head portion 212, which can help break the bubbles. In addition, the included angle α is within the angle range, so that the gas flowability is not affected by the excessively small angle, and the gas can be smoothly discharged out of the bubble breaker 200, thereby avoiding the generation of secondary bubbles in the bubble breaker 200.

Illustratively, the height of the neck portion 214 of the bubble-breaking funnel 210 may be greater than or equal to 3 mm. Since the vapor may generate liquid when contacting the inner wall of the neck portion 214, the neck portion 214 having the height may also allow the generated liquid to dispersedly flow along the inner wall of the neck portion 214, preventing accumulation of the liquid, thereby preventing generation of secondary bubbles.

Illustratively, the cross-sectional area of the airflow passageway within the neck portion 214 of the bubble-breaking funnel 210 may be greater than or equal to 20mm². In the embodiment shown in FIGS. 1-2 in which the inner wall of the neck portion 214 is sloped, it is understood that the smallest cross-sectional area is greater than or equal to 20mm². Defining a minimum value for the cross-sectional area of the passage within the neck portion 214 ensures smooth and rapid gas discharge.

Illustratively, the bubble breaker 200 may also include a bubble breaker return port 230. The bubble breaker return port 230 may be in communication with a first chamber 232. The debubbler return port 230 is disposed outside the debubbler funnel 210. Liquid in the vapor and liquid generated after bubble collapse may flow back into the first chamber 232 outside of the collapsing funnel 210 via the collapsing funnel return port 230. Finally, the liquid flows back to the inner cover 100 and flows back to the pot body through the inner cover exhaust port 101 or the inner cover return port. The debubbler return port 230 can be lower than the upper opening of the debubbler funnel 210. That is, the debubbler return port 230 can be disposed below the upper opening of the debubbler funnel 210. Thus, for the bubble breaker 200, the gas in the first chamber 232 is discharged upwards through the bubble breaking funnel 210, the liquid flows back into the first chamber 232 from the outer side of the bubble breaking funnel 210, the gas and the liquid are separated, and the backflow liquid is prevented from entering the bubble breaking funnel 210 to form secondary bubbles.

Illustratively, as shown in fig. 1-3, the cover may further include a panel 400. The panel 400 is positioned above the inner lid 100 and the bubble breaker 200. The panel 400 may be provided with an upper cover 410. The bubble breaker 200 communicates with the outside through the upper cap 410. For example, the upper cover 410 may include a micro-pressure upper cover, which is used to limit the discharged gas, so as to generate a certain pressure in the pot, thereby forming a high pressure in the cooking device to aid in cooking. Of course, a certain pressure may not be maintained in the pot body through the upper cover 410. The lid 410, the bubble breaker 200 and the seal 500 enclose a second chamber 234. The second chamber 234 communicates with the bubble-breaking funnel 210 and the upper cap 410. The gas separated by the bubble breaker 200 may exit the lid from the upper lid 410 after entering the second chamber 234. The second chamber 234 can play a role of buffering, even if a small amount of bubbles enter the second chamber 234, the bubbles can be broken due to the rapid expansion of the volume, and the liquid flows back into the first chamber 232 through the bubble breaker return opening 230 of the bubble breaker 200, so as to avoid generating bubbles at the air outlet of the upper cover 410.

Illustratively, the cover body may further include a face cover assembly 300. The face cover assembly 300 is sandwiched between the inner cover 100 and the panel 400. The inner lid 100 may cover the lower surface of the face cover assembly 300. The panel 400 may be overlaid on the upper surface of the face cover assembly 300. The face cover assembly 300 may be provided with a through-hole 310. There is also sufficient space within the cavity formed by the upper cover 410, the through-hole 310 and the inner cover 100 to mount the bubble breaker 200. In the embodiment shown in fig. 2, the through-hole 310 may be a cylindrical through-hole extending in a vertical direction. The through hole 310 may be used to mount the bubble breaker 200. The bubble breaker 200 may pass through the through hole 310.

The sealing member 500 also seals between the upper cover 410 and the sidewall of the through-hole 310. Illustratively, the seal 500 may be clamped between the bubble breaker 200 and the sidewall of the through-hole 310 and the upper cover 410, thereby achieving sealing between the bubble breaker 200 and the sidewall of the through-hole 310 and sealing between the upper cover 410 and the sidewall of the through-hole 310. The same sealing member 500 forms a seal between the bubble breaker 200 and the sidewall of the through hole 310 and between the upper cover 410 and the sidewall of the through hole 310, so that the number of parts of the cover body can be reduced, and the processing cost can be further reduced.

Illustratively, the seal 500 may be disposed through the through hole 310. The upper end of the sealing member 500 may be clamped between the upper cap 410 and the sidewall of the through-hole 310, and the lower end of the sealing member 500 may be compressed by the inner cap 100. In the embodiment shown in fig. 2, the seal 500 may be of a cylindrical configuration, i.e., substantially in the form of a seal ring. The upper end of the sealing member 500 is clamped between the upper cover 410 and the sidewall of the through hole 310 to hermetically connect the upper cover 410 and the face cover assembly 300, and thus, gas is prevented from entering the cover body through a gap between the upper cover 410 and the sidewall of the through hole 310. The lower end of the sealing member 500 may pass through the through-hole 310 and have a certain extended length. When the inner cap 100 is mounted on the lower surface of the face cap assembly 300, the inner cap 100 may compress the sealing member 500, thereby closely adhering the sealing member 500 to the upper surface of the inner cap 100. Thus, the gas cannot flow into other positions (where electric components such as an operation panel, a circuit board, and the like may be provided) in the cover body in the horizontal direction. The cover body with this arrangement can discharge the discharged gas out of the cover body through the bubble breaking funnel 210 and the upper cover 410 in order without entering other positions between the face cover assembly 300 and the inner cover 100 and between the face cover assembly 300 and the panel 400, thereby protecting the electric elements and the like in the cover body.

Illustratively, the side of the seal 500 facing the frothing funnel 210 may be provided with a protruding annular lip 510. The outer side of the bubble breaking funnel 210 may be provided with a connection portion. The connection may be snapped into engagement with the annular lip 510 such that the annular lip 510 is sealingly connected to the outer side of the frothing funnel 210. The structure of the connection portion may be arranged in accordance with the annular lip 510.

In one embodiment, the seal 500 may be disposed between the connection of the bubble breaker 200 and the sidewall of the through-hole 310. The sealing member 500 may have various structures, and the sealing member 500 may be configured to match the structure of the through hole 310 according to the connection portion, so that the sealing member 500 is sealingly connected to the connection portion of the bubble breaker 200 and also sealingly connected to the sidewall of the through hole 310. A preferred embodiment of the seal 500 will be described hereinafter. The connection portion may fix the annular lip 510 in the up-down direction. While the annular lip 510 can be tightly attached to the outer side of the frothing funnel 210, even the elasticity of the annular lip 510 can be relied on to make the outer side of the frothing funnel 210 apply a certain pressure to the annular lip 510, so that a sealing connection can be formed between the annular lip 510 and the outer side of the frothing funnel 210. The sealing connection mode has the advantages of simple structure, convenience in installation and the like.

Illustratively, as shown in fig. 4-5, the connection portion of the break-foam funnel 210 may include an annular flange 221, a sleeve 222, and a snap 223. The annular flange 221 may be formed to extend from the outer side surface of the bubble breaking funnel 210 to the outer circumferential side. The sleeve 222 may be formed extending upward from the outer peripheral edge of the annular flange 221. The annular flange 221 and the sleeve 222 form an L-shaped structure when viewed in cross-section. A catch 223 may be provided on the outer side of the sleeve 222 and may catch with the annular lip 510. In the embodiment shown in fig. 2, the bubble breaker 200 may be inserted into the sealing member 500 having a cylindrical structure from below. During insertion, at least a portion of the snap 223 may ride over the annular lip 510, snapping the bulb breaker 200 into engagement with the seal 500. The clamping connection has the advantages of simple structure, convenience in installation and the like, and particularly, the sealing element 500 has certain elasticity, so that the sealing element 500 and the bubble breaking device 200 can be connected more conveniently through the clamping connection.

Illustratively, the annular flange 221 may be provided with a bubbler return port 230. The bubbler return port 230 is in communication with the first chamber 232. The bubbler return port 230 may be a through hole provided on the annular flange 221. Although the vapor and the gas generated by the bubble breaking can be discharged through the bubble breaker 200, the liquid will flow back along the inner wall of the bubble breaking funnel 210, but some liquid may flow onto the outer circumferential wall of the bubble breaking funnel 210 and flow down along the outer circumferential wall of the bubble breaking funnel 210 when the vapor and the gas are discharged. The provision of the bubble breaker return port 230 in the annular flange 221 enables the liquid on the outer peripheral wall of the bubble breaker funnel 210 to be returned, thereby preventing the liquid from accumulating outside the bubble breaker funnel 210.

Illustratively, the annular flange 221 may be disposed at a lower portion of the frothing funnel 210, i.e. in a vertical direction, and the annular flange 221 may be disposed at a position of the frothing funnel 210 near its lower opening. The cross-sectional area of the lower portion of the frothing funnel 210 is larger, and the circumferential length of the annular flange 221 is larger closer to the lower opening of the frothing funnel 210, so that the annular flange 221 can have a sufficient amount to provide sufficient mechanical strength to be able to support the entire frothing funnel 210.

Illustratively, the bubble breaker 200 further includes a hand-held portion 260 disposed on the bubble breaking funnel 210, as shown in fig. 5. As shown in fig. 2, the handle 260 may extend from a lower edge of the bubble breaking funnel 210 down into the first chamber 232. Illustratively, the handle portion 260 may have a generally cylindrical configuration as shown to provide sufficient mechanical strength to the handle portion 260. In other embodiments not shown, the handpiece 260 may also have other configurations, such as extending to conform to the tendency of the sidewalls of the head portion 212 of the frothing funnel 210 to extend. However, in this case, the liquid flowing back through the bubbler return port 230 may fall down onto the outer side of the hand grip 260. Alternatively, the handle 260 may also be one or more spaced apart lugs disposed on the lower edge of the break funnel 210, for example. As previously mentioned, the bubble breaker 200 may be mounted to the seal 500 primarily from below. The extension of the handle 260 into the first chamber 232 may facilitate grasping and mounting of the bubble breaker 200 by a user.

Illustratively, the catch 223 may include a first catch 240 and a second catch 250 spaced apart in a vertical direction. The annular lip 510 of the seal 500 may be captured between the first and second lands 240, 250. The first and second abutments 240 and 250 may protrude in a radial direction from the outer peripheral wall of the sleeve 222. The first and second stages 240 and 250 may form a space in a vertical height. Therefore, when the annular lip 510 is clamped between the first clamping platform 240 and the second clamping platform 250, the first clamping platform 240 and the second clamping platform 250 can form a mounting limit for the bubble breaker 200 in the vertical direction, and the bubble breaker 200 is limited from moving in the vertical direction.

Further, the first chuck 240 may be plural. The plurality of first clamping stages 240 may be disposed at intervals along a circumferential direction of the sleeve 222. The first catch 240 may be a wedge-shaped protrusion that may abut an upper portion of the annular lip 510 of the seal 500. The first clamping platforms 240 are arranged at intervals in the circumferential direction, so that the use of materials for the bubble breaker 200 can be reduced, and the product cost is reduced. When the bubble breaker 200 is installed, the first clamping bases 240 arranged at intervals can reduce the contact area between the first clamping bases 240 and the annular lip 510, so that the force required when the first clamping bases 240 pass over the annular lip 510 can be reduced, and the installation is convenient.

Alternatively, the second chuck 250 may be plural. A plurality of second catches 250 may be spaced apart along a circumferential direction of the sleeve 222. The second chuck 250 may have a similar structure to the first chuck 240. The second chuck 250 may have other structures as long as the top of the second chuck 250 may abut against the lower portion of the annular lip 510 of the seal 500. The second clamping platforms 250 are arranged at intervals in the circumferential direction of the sleeve 222, so that the use of materials for the bubble breaker 200 can be reduced, and the product cost can be reduced.

Further, the second chuck 250 may face the first cavity 232. The second chuck 250 may include a transverse portion 251 and a longitudinal portion 252. The lateral portion 251 extends from the outer side surface of the sleeve 222 to the outer peripheral side. The transverse portion 251 may generally be in the form of an annular structure that fits over the sleeve. The longitudinal portion 252 may extend upward from the outer side edge of the lateral portion 251. Thus, the cross-sections of the transverse portion 251 and the longitudinal portion 252 may be L-shaped, as shown in FIG. 5. The longitudinal portion 252 is spaced from the outer side of the sleeve 222. An upper portion of the longitudinal portion 252 abuts a lower portion of the annular lip 510 upon installation. Because longitudinal portion 252 is spaced from sleeve 222, longitudinal portion 252 can engage annular lip 510 more closely adjacent the root of annular lip 510. The root of annular lip 510 is located where annular lip 510 joins the cylindrical portion of seal 500. Here, the annular lip 510 has the greatest strength and the least elasticity, and thus is more firmly engaged with the longitudinal portion 252. Also, as previously described, the bubble breaker 200 is generally inserted from below the seal 500 into engagement with the annular lip 510. Therefore, the bubble breaker 200 can be mounted in place by applying a certain external force to the bubble breaker 200 upward while the annular lip 510 and the longitudinal portion 252 are more firmly engaged with each other, and there is no fear that the second locking piece 250 also gets over the annular lip 510 and is excessively mounted.

Illustratively, in an embodiment where the first and second lands 240 and 250 are both plural and the plural first and second lands 240 and 250 are both disposed at intervals along the circumferential direction of the sleeve 222, the plural first and second lands 240 and 250 may be staggered along the circumferential direction of the sleeve 222. As shown in fig. 4, the first clamping table 240 and the second clamping table 250 are arranged in a staggered manner, so that the number of the first clamping table 240 and the second clamping table 250 can be reduced when the first clamping table 240 and the second clamping table 250 are ensured to be capable of stably connecting the foam breaker to the sealing member 500, thereby reducing the use of materials and facilitating installation.
